In thedrawings V The forward end of the bolt 15 is formed Figure 1. is a topplan view of a rail lockwith a beveled striker 21, which as the ingdevice embodying my invention. members are being closed will contactwith 59 Figure 2. is'a sectional view of the same the upper edge of thedovetail 13 and force the bolt back against the action of the spring 20.

For operating the bolt 15, there is provided a finger piece 22, whichslides on the lower 5 surface of the member 11 and is secured to theblock 18 by the screw 19, so that by a pull on said finger piece 22 thebolt 15 will be withdrawn from engagement with the member 10. In theconstruction shown in Figures 6, 7 10 and 8, the bolt is mounted in thedovetail 14 and a lug 2 1 formed on the member 11, which havealinedholes therein; and a spiral spring is placed on said bolt 15between said dovetail 14.- and the lug 24; a pin 25 being 15 placed insaid bolt 15 to engage the end of the spring 20, to retain said bolt 15in the normal position as shown.

For operatingsaid bolt 15 against the action of the spring 20, the bolt15 near its 20 rear end is formed with a vertical slot 26, within whichis mounted the arm 27 of a bell crank which is'pivoted in a bifurcatedlug 28 formed on the bottom of the member 11; said crank, having an arm29 provided with a button 30 extending through a hole 31 in the bottomof the member 11 in such a manner that by pressing said button 30 thebell crank will drawback the bolt 15. 7

It is understood that the button 30 may pro- 30 ject beyond the member11, or be flush with its surface, or be in a depression in the same asdesired, or it may be on the side instead of on the bottom. I

It is also to be understood that the looking at bolt 15 may be operatedin place of the two methods shown, by a knob, which by the turning ofthe same will withdraw the bolt, or a key may be used for the samepurpose if desired. 40 Having thus described my invention, what I-claimas new and desire to secure by Letters Patent, is.

In a marine hinged guard rail locking device, and-in combination withtwo engaging 4| rail members formed with recessed ends for attachment tothe adjacent ends of the guard rail, one of said members formed with adovetail slot adapted to engage with a-dove-tail lug on the other memberto form a joint between said members a lug formed within the recess ofone member, a bolt slidably mounted therein and in the end of saidmember and engaging the end of the other member, a spring mounted onsaid bolt between said lug 5 and the end of the member to retain saidbolt in a locked position, and a releasing finger operated means securedto said bolt for withdrawing the same.

In testimony whereof" I afliX my signature.
